Scarlett Johansson says her male Marvel co-stars like Chris Hemworth, Mark Ruffalo, Robert Downey Jr. and Captain America are more "in touch with their feminine sides" than people might think

Scarlett Johansson claims her male Marvel co-stars are not very "macho".

The 31-year-old actress has portrayed Black Widow in a number of movies in the franchise, including 'The Avengers', 'Iron Man' and 'Captain America', and has found the likes of Chris Hemsworth, who plays Thor, Robert Downey Jr. (Iron Man), Mark Ruffalo (Hulk), and Chris Evans, who portrays Captain America, are much more "feminine" than people would think.

She said: "They want me to say they are macho but they're in touch with their feminine sides - some of them spend more time in the hair chair than me ... Hemsworth."

Scarlett - who is married to art dealer Romain Dauriac - shot much of 'The Avengers: Age of Ultron' while pregnant with daughter Rose, now 20 months, and though it was a "surreal" experience, she insists no one on set treated her differently.

She said: "It was so surreal. But soon after we started shooting, it was liberating.

"I was like, 'And what? This is how it is. Maybe I didn't get thrown around as much but nobody treated me any differently."

The blonde beauty - who was previously married to Ryan Reynolds - is currently training to play a cyborg cop in sci-fi thriller 'Ghost in the Shell' and is finding juggling her preparations with ordinary home life quite strange.

She told Cosmopolitan magazine: "I get up, pour the ol' bowl of Cheerios, take care of le bebe, make sure she's all set, then I go fight, kickbox, and do Filipino stick training and tactical weapons training.

"I get the s**t kicked out of me and then it's night time and I go home, make dinner, wash le bebe, pop her in her little bedtime place and hit the hay."
